In astrophysics when we discuss the metallicity of an object we are referring to the content of elements heavier than hydrogen and helium. Unlike what we normally consider metals, a metal in astrophysics is any element other then hydrogen or helium. There are a few ways to calculate or determine the metallicity of a object which include, 1. Mass fraction 2. Chemical abundance ratio 3. Photometric colours It can be useful to know if a star has high or low metallicity as it can alter its colour and he likelihood of hosting planets. |
